SELF-THREADING LO'OIiVI-SHU'TTLE.

srncirrcn'rron forming art of Letters Patent No. 559,306, dated April28, 1896.

Application filed February 12, 1896. Serial No. 678,992. model.)

To all whom it may concern:

Be it known that I, PATRICK J. OGoNNELL,

of Hopedale, county of Worcester, State of Massachusetts, have inventedan Imprvement in Self-Threading Loom-Shuttles,,of which the followingdescription, incoiinec-J tion with the accompanying drawings, is aspecification, like letters the construction of which is hereinaftermore fully described and claimed.

Figure 1 shows a shuttle containing my improvements; Fig. 2, an enlargedtop View of the delivery end of the shuttle;, Fig. 3, a like view of theend of the shuttle with the selfthreadingdevice removed. Fig. 4 shows aninner end view of ;-tiie*seif-'threading" device detached; Fig. .5, aside elevation thereof,

Fig. (i, an inner side view'of one half of the device; Fig. '2, an innerside view of the other half of the device; Fig. 8,'an outer or front endview of the self-threading device with the end of the finger cut on, andFig-9.an under side View thereof.

The open shuttle-bodyA and the bobbin 1),

havinga cop c of thread, are and may be all as usual. The top side ofthe frontend of the shuttle-body is out out or chambered, as best shown.in Fig. 3, to leave a circular chamber a with a larger'eircular chamberb at its-upper end, a point-receiving chamber bleading from the ehambera'toward the end of the body. .The' chamber a is intersected by twopassages-b b the wall of the shuttle-body at the end of the passage bhaving a slot b,,which leads to the deliveryeye 0 thus making that eyeopen .for the (49'. i

HThe-selE-threading device is composedof.

reception of the'bobbin-thread.

two half-circular parts (1 6, having, respectively, faces d c, whichabut together, a pin j d on the part d entering a hole 6 in part c and apin (2 in part e entering a hole d -in part at the said pins supportingthe bobbinthrea after the latter has entered theselfthreading device.The art d has a forwardly-e'xtended finger d recessed at its inner sideto leavean overhanging flange d and a gliidaspace (1 and the top of part(Z on h rawin is provided with an annular semiflange d to enter therecess b The half e is-widened to form a flange c5 and has-a'forwardly-extended horn e provided with an inwardlyextended lip ewhich enters the space at the inner side. of the finger (1 below theflange d a slotbeing left between the flange of the fingerand the lip ofthe horn for the threadicaught under the point of the 110m draws underthe horn and. is,by its down wardly-curved breasts and its outerinenne'aguidm edgavmece ,totravei' in the space f between the horn andthe inner wall of the space 12" of theshuttle-body, and ar-;.

riving at the shoulder e' will enterthe open delivery-eye c. I

- The threadingdevice is held in the shuttle by a screw 'g, which entersthe shuttle at its side rather than at its bottom, as heretofore,

and said screw, besides holding the device in theshuttle, also acts tohold together the two parts d 'e of the device. Where the screw forholding the threading device is inserted through the-bottomj-of theshuttle, it will be obvious that the shuttle is weakened in thedirection of its length and in the line of the open chamber receivingthe bobbin or fillingcarrier, and therefore the tendency of the shuttleto split lengthwise is greatly increased; but by inserting-the screwthrough the side of the shuttle the splitting of. the

shuttle is also obviated. By making each partd and e separately they maybe cast in a mold, thus obviating cutting-slots and mil 1-. ingoperations, which are very expensive.

I-Iaving .described my'invention, what I claim as new, and desire tosecure by Letters Patent, is g A 1; A shuttle-body having areceiving-chamwall an open delivery-eye communicating with said chamber,combined with a'selfthreading device composed of two separate,

her at its upper side and having in its side detachable parts, one ofsaid parts being made as a finger having its inner side recessedlongitudinally to leave an overhanging flange 61 the other part,designated as a horn,. having a pointed lip to enter the recessbelow'the said flange, a downwardly-inclined breast e and outer inclinedguiding edge, the said guiding edge forming one side of thethread-guiding slot through which the thread travels into the opendelivery eye, substantially as described.

2. A shuttle-body having a receiving-chamber at its upper side andhaving in its side wall an open delivery eye communicating with saidchamber, combined with a selfthreading device composed of two separate,detachable parts, one of said parts being made as a finger having itsinner side recessed longitudinally to leave an overhan ing flange. d,the other part, designated as a horn, having a pointed lip to enter therecess below the said flange, and a screw passing through the side ofthe shuttle-body and entering and holding together the said separatedetachable parts, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
